Specification of Letters Patent.

Application filed April 4, 1917. Serial No. 159,765.

To all whom it may concern:

Be it known that we, An'ronr. A. BOWEN .and ROBERT M. Prams, citizens of the United States, residing at Fresno, in the county of Fresno and State of California, have invented certain new and useful Im' provements in Sanitary Toilets, of which the following is a specification.

Ourqinvention relates to thejiclass or;

The object of the invention is hygienic,'a;

' result reached through a sanitary measure f,-applied,'to the toilet" seat, whereby "said seat in 'a'oondition"donducive to -1s maintained health.

' To this end our invention consists in the .hnovel toiletwhich we shall hereinafter fully describe and illustrate in the "accompanying drawings, it being understood that both de scription and drawings disclose the invention in its a and alterations may be made 'within the scope of the claims a'ppended,with'out departin from thdspirit of the invention.

In t e drawings' Figure 1 is a sideelevation, partly in section, of the toilet.-

Fig.2 is atop plan of the sameg 4 Fig. 3 is a longitudinal section; enlarged, of the seat and its adjacent connections for supplying a liquid disinfectant, the section of the seat and binge being on the line 3-3 of Fig. 4.

Fig. 4 is a broken top lan view of Fig. 3.

1 is the bowl of the toi et, and 2- is-its seat.

To avoid confusion the usual lid is omitted." 3 is the "watefiflushing tank, commumcat ing with the bowl through a connection 4.-

The communication is controlled by a valve 5 adapted to be lifted by its stem 6 connected with a rock shaft 7 operated by an exterior handle 8. Water is supplied to the tank from a pipe 9 having a out 01f cock at 10. The pipe 9 is automatically controlled by a valve 11 operated by a float 12. All these parts constitute a commonstandard form of toilet and are intended to represent and stand for any toilet. Their special construction and arrangement, are not, however, cs-

sential, it bein understood the our invention as hereina ter pointed out 18 applicable to any form or construction or arrangement of water-flushed toilet.

referred fornnjthough changes seat is down on the According to our invention, the seat 2 has fitted to it, or is provided or formed with a perforated encircling fluid conduit in such position that it is adapted to deliver a liquid along the outer border of its upper surface or face, so that said liquid will flow inwardly over and cover and wet the inward sloping facaof the seat, the surplus thus flowing into the bowl. v The gpecific construction and disposition of this uid conduit may be varied; but, for

illustration, we show and prefer a form of seat Z';-*-m'ade" of suitable material, say, for

"' exainple', aluminum, having in its upper portion near its outer border a conduit 13 provided with perforations 14 adapted to deliver the li uid contents of the conduit upon the'upper ace of the seat, all around its circumference.

" In order to supply the seat with liquid we p'rovide a second tank 15, which in practice "iscontrolled 'by a gravity valve 17 the stem 18 of which is connected with the rock shaft 8 of the water flushing tank, in such relation that the water flushing of the bowl, due to the operation of the rock shaft is simultaneous with the discharge of the liquid from the compartment 15 to the seat 2.

The discharge connection 16 from the compartment 15 communicates with the conduit 13 of the seat 2 through the seat hinge, which hinge is of a character to permit the passage: of the liquid, while still permitting *theusual hinge movement of the seat to lift and lower it, as is common.

This hinge is, also, a valve to control the flow, said valve bein open, only when the owl, but closed when the seat is raised, thereby permitting the water-flushing of the bowl when the seat is elevated, without delivering any liquid from the supplementary tank or compartment 15, and thereby avoiding waste ofsaid liquid, the small amount remaining in the conduit 13 and tending to flow out through the lower perforations thereof being negligible. This valve-hinge ma be of any suitable char acter. A good orm is that here shown, particular reference being bad to Figs. 3 and 4. A pair of arms 19 extend rearwardly from the back of the seat, and are pivotally mounted on a cross bolt 20, carried by a block 21, which seat is itself carried by the stem 22 of the discharge connection 16 from the supplementary tank or compartment 15.

In the back of the block 21 is made a passage 23 from end to end, with which the passage through the stem 22 of the connection 16 communicates. In each end of the block 2]. is made an arcuate port 24. l/Vith the rear end of each port 24, the passage 23 communicates permanently. In each seat arm 19 is made a passage 25, the rear end of each passage 25 registering with the forward end of the arcuate port 24, when the seat is down in its normal position on the bowl, but moving out of registry therewith when the seat is lifted from the horizontal. The forward end of each armpassage 25 communicates with. the conduit 13 in the seat In Fig. 3, we have shown a screw plug 26, the adjustment of which-controls the passage through the connection 16, whereby the rate of flow of liquid supplied may be initially determined and regulated.

The operation of'the toilet is as follows Any suitable liquiddisinfectant is supplied to the supplementary tank or compartment 15. In using the term disinfectant we mean to include any substance used to destroy or restrain the germs or micro-organisms of infectious diseases, whether it acts as a germicide proper, or as an antiseptic to destroy the growth of such micro-organisms 0f putrefactive naturel When the rock shaft 8 is moved, in order to water-flush the bowl, the same movement opens the discharge connection 16, and the liquid-disinfectant from compartment 15, flows into the conduit 13 of the seat 2, and is discharged from itsv perforations 14, over the entire upper face of said seat, the surplus flowing into the bowl. Thus the Seat is purified from infection and kept wholesome and free from contamination, and to the extent that the disinfectant flows into the bowl :1 beneficial result is also had. The disinfectant rapidly dries off so as not to interfcre with the comfortable re-use of the seat.

The flow of the liquid disinfectant stops, with the release of the rock-shaft handle 8, being controlled by the gravity valve 17, but each time the bowl is flushed, the disinfeet-ant flows to the seat.

This is the normal operation of the toilet, assuming the seat to be down on the bowl; but, as heretofore pointed out, if the seat be elevated, as when usin the toilet as a urinal, the bowl may sti 1 be water-flushed, while the seat is raised, but without having a flow of the disinfectant through the valve hinge which is then closed. This avoids any mistake, and the consequent waste of the disinfectant.

Also by properly adjusting the regulating plug 26, the rate of flow of disinfectant is determined so that an unintentionally prolonged holding open of the gravity valve 17 will not result in draining the supplementar tank.

We c aim 1. A toilet comprisin a bowl; a. seat for the bowl having a per orated fluid conduit encircling its outer border in position to deliver its contents over the upper face of the seat; a hinge connection adapting the seat to be lifted and lowered, said hinge having a passageway through it communicating with the conduit of the seat; a double compartment tank for liquids; a valve controlled connection between one of said compartments and the bowl, through which the bowl may be water-flushed from said compartment; a valve controlled connection between the other tank compartment and the passageway of the seat hinge whereby the seat conduit may be supplied with a liquid disinfectant; and a rock-shaft common to and associated with both said valve-controlled connections for opening and closing them in unison.

2. A toilet comprisin a bowl; a seat for the bowl, having a per orated fluid conduit encircling its outer border in position to deliver its contents over the upper face of the seat; a valve-hinge connection adapting the seat to be lifted and lowered, said connection being open when the seat is down on the bowl, and closed when the seat is lifted therefrom; and controllable means for supplying said conduit with liquid disinfectant through the valve hinge connection of the seat when said seat is down on the bowl.

3.
